Moving Red/ Green piece to the right side  

There are only 3 possible scenarios you will face when tackling this middle row. To start, simply look at the 4 edges on the Bottom Layer and find one piece that does not belong on the Bottom Layer.

Once you have found one, simply rotate the Bottom Layer until you form a  “ T ” like shape as shown in the picture given below, and follow the move below given. In this scenario we have to bring the bottom middle edge piece to the right side. This move is very important one. So try to memorize it. Because this is the move we are going to use very often here onwards.

We will call it “ MOVE-1”. Keep in mind this rule. If we want to move the piece to the right side, the first movement will be to the left. In this example we are going to place it to the arrow showing right side, so that our first move is towards the left.

Moving Red/ White piece to the left side

	To make you understand better we have given you another view of this cube. In both images consider red as front.

In the scenario two we have to bring the bottom middle edge piece to the left side. This move is also very important one. Actually this is a reversal of the “MOVE-1”. So try to memorize it. Because this is also a move we are going to use very often here onwards. We will call it “ MOVE-2 ”. Keep in mind this rule. If we want to move the piece to the left side, the first movement will be be to the right. In this example we are going to place it to the arrow showing left side, so that our first move is towards the right.

The third possibility is that a piece is already in place, but backwards, as shown below. Unless the piece is on the bottom row, you will not be able to get it properly in place, so simply put a bogus piece, from the bottom row, in its place - this will force the problem piece to the bottom row so that you can use one of the two methods above (MOVE-1 or MOVE-2) to put it back in place.

Repeat this process for each edge piece and you will have completed the middle layer.
